ICU Associated Weakness and Bedside Ultrasound Assessment

NCT04095533 · Status: TERMINATED · Type: OBSERVATIONAL · Enrollment: 11

Summary

ICU-associated weakness is a common experience for people following a critical illness. It is associated with important patient and system-relevant outcomes. Diagnosing ICU-associated weakness can be challenging because making the diagnosis relies on volitional participation in strength testing by the patient in a very ill population that is often sedated or restrained.

This study proposes to test if bedside ultrasound of tibialis anterior (a non-invasive test that doesn't require active participation by the patient) correlates with clinical whole-body weakness in critically ill patients admitted to an ICU with sepsis.

Conditions

Interventions

OTHER

Tibialis anterior muscle cross-sectional area assessment by ultrasound

Assessed using bedside ultrasound with repeat assessments every second day up to 2 weeks of ICU admission, or until discharge from ICU to yield an overall rate of muscle area decline reported as a %/day average muscle atrophy rate. Tibialis anterior cross-sectional area assessments will be assessed by measurement ultrasound to both legs with portable bedside ultrasound. The cross sectional area will be measured in cm\^2 at 5 cm distal to the lateral eminence of the tibial tuberosity along the muscle belly. Image processing will be performed at the bedside using features available on the ultrasound device. Muscle boundaries will be marked on the device and the cross-sectional area (computed from the perimetral contour of the muscle section) will be determined. This process will be repeated for two times for each leg.

OTHER

Muscle strength assessment

Assessed using clinical bedside evaluation every second day with the Medical Research Council Sum Score. This is a clinical assessment of strength of 6 different muscle groups (shoulder abductors, elbow flexors, wrist extensors, hip flexors, knee extensors, and ankle dorsiflexors) on each side of the body and recorded as a score between 0 (flaccid) and 5 (full strength).
